EXTENSION-TABLE.

Application filedMarch 231908.

To all whom it may concern:

Be it known that we, WILLIAM L. PrerrnRKonN, ALBERT P. ScHLonnB, and AUGUST H. HAMMn'r'rnR, citizens of the i United States, residing at Milwaukee, county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Extension-Tables, of which the following is a specification.

Our invention relates to improvements in extension tables and pertains more particularly to that class of tables known as pedestal extension tables. Heretofore the usual practice has been to form the pedestal in two vertically divided sections which, when in abutting position, form a complete pedestal, the table being then closedor at its smallest dimension. It is necessary in tables of this type to lock the sections together when in an abutting position, as otherwise the sections tend to separate at the bottom and even a slight separation renders the table unsightly.

The object of our invention is to provide a form of construction in which the table will be supported by two complete pedestal posts which will present a finished appearance on all sides-when the table is extended, and which will. approach each other (when the table is closed) without requiring abutting contact at any point and without requiring an absolute alinemcnt of the pedestal members, each of the members, however, being provided with a pair of divergent feet arranged symmetrically with those of the 1 other pedestal, the two complete pedestal members being adapted to move into close proximity with each other, thus securing all the advantages attained in a table having a single divided pedestal withoutexposing the unfinished interior of the pedestal in any position of adjustment and without requiring the use of locks-or latches to hold the members together.

A further object of our invention is to provide means whereby in the larger tables an additional center leg may be employed which can be folded above the bridging and thus permit the pedestal members to come together when the table is reduced in size. The appearance of the table when :so reduced is the same as thosewhich have :no additional :center leg.

In the following description reference 'is Specification of Letters Patent.

' tended position, the customary top boards :being omitted. Fig. 2 is a bottom view of a similar table with an auxiliary center leg and additional slides, the folded position of such center leg being indicated in dotted lines. Fig. 3 is a vertical sectional View of the same in reduced position, with the center leg folded. Fig. 4 is a detail view of the auxiliary leg and the bridging board to which it is attached. Fig. 5-is a similar view showing a modified form of hinge.

Like parts are identified by the same ref erence characters throughout the several views.

Referring to Fig. 1, A and B are the :respective pedestal members, each being provided with a pair of feet ct and 2) :respectively. Bridging boards C and D arem0unted upon the respective pedestal members, and provided with the mutually engaging slides E and F. These slides are rigidly attached to the respective bridging members and permit a longitudinal separation of the pedestal posts A and B. The top part G is provided with rigidly attached slides g movably engaging the outer faces of the slides E and the top board H is similarly provided with slides h which movably engage the inner faces of the slides F, the top boards being thus permitted to move outwardly to some extent independently of the pedestal posts. When reduced to the smallest position this table has the appearance of the table shown in Fig. 3, except thatthe folding post and intermediate bridging board are omitted.

Referring to Fig. 2 it will be observed that the construction is the same as that :shown in Fig. 1 with the exception that ing board I is employed to which the intermediate slides J are affixed and arranged with. therslides E engaging their outer :faces and the slides F engaging their inner faces,

thus permitting a greater extension of the table than is possible with that shown in Fig. 1.

The intermediate bridging board I is provided with a supporting leg L, connected therewith by hinge members M rigidly secured to the top of the bridging board, and members N having jointed connection there with at m, and also having jointed connection with the leg L at a point 41. below the bridging board, thus forming a double jointed hinge which permits the leg to be swung upwardly to a position above the bridging board and resting transversely thereon as illustrated by dotted lines in Fig. 2, and as also shown in Fig. 3. When the leg is in this folded position the pedestal posts A. and B may 'be brought together as illustrated in F ig. 3, the table then having the same appearance as that shown in Fig. 1 when the latter is in closed position.

The upper end of the post L is provided with a tapered pin 0 which is adapted to fit a corresponding socket in the bridging board when the leg is in supporting position. The leg is also provided with a stop P against which one of the hinge members N impinges when the leg is in supporting position, thus giving stability to the leg. The leg is also preferably locked in this po sition by a spring latch Q, connected with the leg and adapted to engage a catch, such as the pin R on the opposite side of the bridging board from that occupied by the hinge members N. 'This latch is manually released when it is desired to fold the leg.

The pedestal feet a and b are provided with ordinary casters S, and other casters T are preferably connected with the inner margins of the pedestal posts, the casters S and T thus forming a triangular support for each pedestal post.

I The pedestal posts A and B are preferably oval in form with the larger diameter in, cross section extending at right angles to a plane common to the vertical axes of the posts. The contour of the pedestal posts, however,'is not essential to our invention, although by the use of oval posts the central axes of the posts are brought relatively close together with corresponding neatness in appearance and greater stability than could be secured by the use of round posts having the same diameter when measured longitudinally of the table. Forthe same reasons a post which is rectangular in cross section would be preferred to a square one.

In Fig. 5 we have shown an auxiliary folding leg pr ovided with a modified form of'hinge comprising a member U fixed to the upper surfaceof the intermediate bridging board, a member V fixed to the post at a point intermediate of its ends, and a link .member W having. hinge connection with the members Uand V at its respective ends.

This hinge permits the post to be folded over the bridging board in substantially the same position as illustrated in Figs. 2 and 3. The form of hinge used is preferably one which allows the central portion of the post to rest upon the bridging board when folded, as this not only allows the post to be balanced on its support, but also facilitates swinging it into position without contacting with the fixed top boards since the double joint permits the upper end of the post to swing downwardly and backwardly while the lower end moves upwardly past the top board.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is,-

' 1. An extension ta.ble,provided with a pair of pedestal posts, oval in cross section and with their longer diameters in planes extending at right angles to a plane common to their vertical axes, and arranged to move into close proximity with each other when the table is in reduced position, and to move outwardly in opposite directions from such position when the table is extended.

2. An extension table, provided with a pair of pedestal posts, oval in cross section and with their longer diameters in planes extending at right angles to a. plane common to their vertical axes, and arranged to move into close proximity with each other when the table is in reduced position, and to move outwardly in opposite directions from such position when the table is extended, each of said pedestal posts being provided with supporting feet, with all of said feet extending divergently from substantially a common point between the posts when the table is in reduced position.

3. In an extension table, the combination of a pair of pedestal posts, each complete in itself and having a finished outer surface on all sides, bridging boards mounted on said posts and slides connected with the bridging boards of the respective posts and having relatively movable connection with each other, said slides being adapted to permit the posts to move into and out of close proximity to each other, but to prevent said posts from coming together, whereby when brought into proximity, the two posts may form substantially one pedestal of symmetrical proportions.

4. An extension table provided with a pair of pedestal posts each complete in itself and each provided with supporting feet co- I operating with the feet of the other post to form a symmetrical support, bridging members connected with each pedestal post, slides fixed to said bridging members, an intermediate bridging member, slides fixed thereto and movably connected with the first mentioned slides, a post having double jointed connection with the intermediate bridging member and adapted to move from a supporting relation thereto to a superposed horizontal position thereon, and top boards movably connected with the first mentioned slides and adapted to meet over the intermediate bridging member.

5. An extension table provided with a pair of pedestal posts each complete in itself and each provided with supporting feet cooperating with the feet of the other post to form a symmetrical support, bridging members connected with each pedestal post, slides fixed to said bridging members, an intermediate bridging member, slides fixed thereto and movably connected with the first mentioned slides, a post having double jointed connection with the intermediate bridging member and adapted to move from a supporting relation thereto to a superposed horizontal position thereon, and top boards movably connected with the first mentioned slides and adapted to meet over the intermediate bridging member, vsaid pedestal posts being arranged to also substantially meet under such bridging member.

6. In an extension table, the combination of a pair of separable pedestal posts, each complete in itself and movable into and out of close proximity to the other, bridging boards connected with said pedestal posts, an intermediate bridging board, and a leg having hinge connection therewith, said hinge connection being provided with an intermediate link pivotally connected at its respective ends and extending upwardly across one margin of the bridging board, whereby the leg is permitted to revolve from a supporting position underneath the bridging board to a superposed position with the lower portion of the leg extending across the bridging board.

7. In an extension table, having a centrally disposed bridging board, the combination with such bridging board, of a supporting leg therefor provided with a hinge member connected with the leg and extend ing across one side margin of the bridging board and pivot-ally supported from the bridging board at a suflicient height to allow the leg to revolve about the bridging board until the lower end of the leg swings across the upper surface of the board to a substantially horizontal position.

8. In an extension table, the combination with a bridging board, of a supporting leg therefor, a hinge member connected with the bridging board and provided with a pivot hearing at one side of and above the board, another hinge member having one end engaged in said pivot bearing and another end pivotally connected With the leg below the bridging board, a projection connected with the leg and adapted to be engaged by said last mentioned hinge member when the leg is in a supporting position, said leg having no other fixed connection with the bridging board.

9. In an extension table, the combination of a bridging board, a leg having its upper end loosely socketed in said bridging board and a hinge connection between said bridging board and leg arranged with one member extending across one margin of the bridging board and other members pivoted to the first mentioned member and also pivoted to the opposing sides of the leg below the bridging board and adapted to permit the lower end of the leg to revolve around the bridging board to a superposed position with said portion of the leg extending across the bridging board.

In testimony whereof we aflix our signatures in the presence of two witnesses.
